You'll need more than just an account to access "certain mature content" on sites like Reddit - you'll soon need to upload some photographic ID.
Make no mistake, the plan is to require 'KYC' for Google, reddit, Facebook, X soon and all that and then later require it for all web sites, even this one.
Australia recently passed a law requiring Google to KYC Australian account holders to check ages to decide if the user will be allowed to control the "safe search" setting.
There will always be something you could maybe do as a workaround, but they are going to make it extremely hard.
